Microsoft product manager and frequent flier Angus Logan believes that, when flying: "When the person in front reclines your productivity declines," and he's set out to do something about it.

Logan's trick: He wedges a water bottle between his tray table and the seat ahead of him to prevent the person in that seat from reclining. The suggestions don't end there, but the water-bottle trick is by far the most clever suggestion for a desperate situation. It's not the neighborliest thing to do, and the post is written a bit tongue-in-cheek, but you also get the impression that Logan is serious about getting things done on his flights.
